AssIGN-on T0 AKTIEBOLAGET CATCI-IING MEMBER FOR THE MOVEMENT MEAT SLICING MACHINES.

A'pplication filed May 5,

To all w/mm it may concern.

Be it known that I, JosEr AUGUST Non- DIN, a subject of the King of Sweden, residing at Gotgatan 14, Stockholm, in the Kingdom of Sweden, have invented certain new and useful Improvements in Catching Members for the Movement of Meat-Slicing Machines, of which the following is a specification.

In meat slicing machines the movement of the table, carrying the meat, t

owards the plane of the disk knife generally is effected in en agement with a screw-thr turning the nut segment into 1e movement will cease when the segment leaves the screw-thread.

y means of a nut segment or the like being eaded spinnut For reengagement segment has been used.

The present invention relates ing member.

to a catchwhich compared with arrangements hitherto employed for the same purpose ofiers the advantage of simpler construction.

her in question is not sensitive parts or parts sequently is tenable.

An embodiment of the invention is illustrated in the accompanying drawing, in is a side view of one end of the the latter as well as part of the spindle being shown in are sections through the line ab the catching member being Fig. 4; is a a slightly modified form of which Fig. l spindle and the nut segment,

sectional view of the invention.

The threads 2 of being of a The catching memprovided with any easily exposed to wear such as springs and slippers and conthe spindle 1 are turned off at 3 and consequently the nut segment 4 owing to the rotary movement of the spindle in one direction having been moved to a certain end position will leave the ment with the threads and slide the spindle whereby the feed of engagefreely on the table (not shown in the drawing) connected to said nut segment will come to a standstill.

A stop 5 limits the movement segment in its direction screw-threads.

ment is a groove the like the latter being pivotal on a screw 8 screwed into the n of the nut away from the Provided in the nut se or recess 6 for apawl 7 or ly mounted ut segment.

1923. Serial Nd. 636,908.

The pawl 7, which is always resting above the screw-threaded part of the spindle and rotatable in a plane at right or nearly right angles to said spindle, on account of its own weight tends to adjust itself with its free end in engagement with a thread.

On the rotating of the spindle in one direction (see Fig. 2) the pawl owing to its own weight and the friction resistance of the screw-threads of the spindle will bear against a shoulder 9 on the nut segment and thus be still in engagement with the screwthreads and, consequently, the nut segment will be returned to engagement with the threads. When the rotary movement of the spindle is reversed and the nut segment has reached the end of the screw-thread the pawl will be moved outwardly from the screw thread (see Fig. 8) so that the nut segment is automatically released. The pawl will normally be turned out of and fall down in thethreads, if the rotary movement of the spindle is continued in the direction last named. In order to facilitate the sliding up of the pawl its free end is bevelled as shown at 10 in Fig. 1.

The lifting up out of and turning down of the pawl into the screw-threads is efi'ected without those disturbing clicks, which generally take place by using spring actuated pawls of the type hitherto known.

The embodiment shown in the drawing presupposes that the nut segment and paw] are mounted vertically above the spindle so that the pawl may turn down of its own weight towards the screw-threads. The pawl may, however, if preferred, also be actuated by a spring 11 tending to turn the same towards the threads as shown in Fig. 4. In this case the nut segment will not of course be mounted vertically above the spindle but may be placed in any position desired.

I claim:

1. A catching member for the movement of meat slicing machines comprising in combination with a rotating screw spindle and a nut segment engaging the spindle, a pawl pivotally mounted on the nut segment in such a way that its axis of rotation is par allel with the axis of the spindle so that when the spindle is rotated in one direction the pawl is by friction action from the spindle caused to move in a plane at substantially right angles to the axis of the screw spindle and thus be disengaged from the screw thread thereof, and a shoulder on the segment for preventing said pawl from being turned out of engagement with the screw thread when the spindle is rotated in the opposite direction.

2. A catching member as claimed in claim 1, wherein a spring is terminated on the pawl and tends tomove the pawl into engagement with the screw thread and 10 forces the same into the shoulder, substantially as and for the purposes set forth.

In testimony whereof I have alfixed my signature in presence of two witnesses.
